1.2 General information
The purpose for this document is to provide instructions for
unpacking, storage, installation, and commissioning of Power
Xpert XGIS gas insulated switchgear (referred to as Type XGIS gas
insulated switchgear from this point forward). These switchgear
vertical sections employ state-of-the-art gas insulation, shielded solid
insulation, vacuum interrupters, and modular plug-in technologies.
Combined with laser welding technology and a helium gas leakage
testing process, this system provides high reliability and a small
installation footprint. They provide reliable control and protection for
electrical equipment and circuits, up to 38 kV.
XGIS switchgear is designed for reliable performance, ease of
handling and simplified maintenance. In addition, XGIS switchgear is
tested to IEC standards for application around the world.
The XGIS switchgear has been tested to the seismic requirements
contained in the IEEE 693 standard, the International Building Code
(IBC 2015), and the California Building Code (CBC 2016). For more
information, refer to Seismic Certificate Number SA022006EN.
XGIS gas insulated switchgear vertical sections incorporate
technology intended to make the XGIS system smaller in size, easier
to install, more reliable and easier to maintain than air-insulated
switchgear.
XGIS vertical sections come in five configurations. Options are
available to customize the equipment for each application. The five
configurations are
•
Feeder/incoming
•
Bus tie
•
Bus sectionalizer
•
Disconnector
•
Cable connector
The XGIS switchgear vertical sections come with standard and
optional features. All of the vertical sections include a pressurized
tank filled with SF
6
, (sulfur hexafluoride).
All XGIS vertical sections are designed for bottom entry of the power
cables. All XGIS vertical sections are designed for top or bottom
entry of low-voltage power and control wiring.
An option of the XGIS design is available that is certified to IP4X
requirements.
The XGIS design is not rated for outdoor service.

elements. Figure 2 shows the details of the medium voltage power
components and control elements.
Figure 3 and Figure 4 show XGIS system power components for a
1250 A standard section and a 1250 A bus tie section.
